Somebody please help. We have an odd little problem that has been driving us crazy. We are using Toshiba 1000 laptops running Procomm (not plus) as VT100 terminals to talk to Northern Telecom fiber multiplexers. They have been very reliable and cost effective. The problem is, sometimes the laptop crashes. We have traced this to the data logger feature in the multiplexer. It seems this allows the mux'er to send error messages THROUGH a VT100 terminal to an attached printer. Problem: the laptops don't have a printer attached, so the terminal emulator bombs with a message to the effect that "device PRN not found". We have sort of solved the problem by issuing the following kludge: MODE LPT1: = COM2: which dumps the attempted print into the bit bucket because there is no COM2 on a T1000. This does not work however, on any other laptop because: 1. Most laptops have a later DOS than the T1000's 2.11 2. Later versions of the MODE command check for the existance of a device before allowing a diversion. What we need is something that will divert the PRN: device to NUL: Does such a thing exist? If so, could somebody mail it to me (I can't FTP)? -- ------- Jim Harvey | Michigan Bell Telephone Co. | "Ask not for whom the Bell Tolls and you 29777 Telegraph Rm 3352 | will only pay station to station rates."

If so, could somebody mail it to me (I can't FTP)? I use a TSR called PRN2FILE to redirect printer output to disk file. I just tried loading it and redirecting to 'nul'. I pressed PRTSCR and watched the cursor scan my screen. No file called 'c:\nul' appeared, (though the program claimed to be redirecting to that name). Seems to work. It's available from simtel. -jeff-
